AEROPLANE.

Application filed October 31, 1927. Serial No. 230,085.-

This invention relates to improvements in aeroplanes and has for an important object thereof the provision of auxiliary pivoted planes which may be shifted to check the motion of the aeroplane to enable landing upon their respective surfaces.

Another object of the invention, resides in the provision of an auxiliary plane of this character which when in use'has means for braking the aeroplane and will not tend to make the same nose downwardly.

A still further important object of the inventionresides in the provision of an improved aeroplane of this nature which is exceed-ingly simple in construction, easy to operate, fairly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other'ob ects in view, as will appear as the description proceeds, the invention. resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is 'a side elevation of an aeroplane embodying the features of my invention,

Figure 2 is a fragmentary sectional view taken substantially on the line 22 of Figure 1; and

Figure 3 is a fragmentar longitudinal vertical section taken substantially on the line 33 of Figure 2.

Referring to the drawing in detail, it will be seen that the numeral 10 indicates the'fuselage of the aeroplane, the numeral 11 the planes thereof. While in all instances the aeroplane has been illustrated as being of the ferred manner and has a link 17 projecting function as brakes to retard the aeroplane so as to allow the same to land in a restricted area. ,It Wlll be seen by having the auxiliary planes hingedly mounted at their forward edges to theforward edges of the planes of the aeroplane that nosing of the aeroplane is prevented because these auxiliary braking planescreate. a resistance which would tend .to lift the nose of the fuselage.

It is thought that the construction, operat1on and advantages of this invention will now be quite apparent to those skilled in this art without a more detail description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice, it attains the features of advantage enumerated as desir able in the statement-of the invention and the above description. It is apparent that changes in the details of construction, and'in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter clalmed or sacrificing any of its ad vantages.

Having thus described our invention, what we claim as new 1s:

In an aeroplane, a fuselage, a lower wing structure including a pair of sections projecting laterally from the fuselage one to each side thereof, struts rising from the sect-ions,

bi-plane type, it will hereinafter become ap\ an upper wing structure on the struts across parent that the principal construction employed with my auxiliaryplane-may be applied'to monoplanes or any of the multiple plane types with the same result.

In accordance with my invention, in the" present example, thelower plane 12 has a shaft journaled in forward struts 13 so as to lie along the forward edge of the'bottom plane. Auxiliary planes 14'are fixed to the shaft 12'and normally extend rearwardly on top of the plane 11. A'crank 15 is attached to the shaft 12 in the fuselage 10 as illustrated to advantage in Figure 3. A lever 16 is pivotally mounted in the fuselage in any prethe top ofthe fuselage, a pair of planes,

means hinging the forward ends of the planes between the forward struts immcdiately above the Wlng sections and adjacent their forward edges, said pair of planes being adapted to normally rest upon the top sur-. faces of the wing section and within the confines of their contours, and means for swinging the planes to angular positions in respect to the wing sections.-
